Lactic Acid Fermentation:

It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells.

Alchoholic Fermentation:

Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

linnaeus is the father of taxonomy, which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
